Pre-operation
ADJUSTING FAN PATTERN
The angle of spray may be adjusted on some
lances by rotating the nozzle.
This will vary the spray pattern from approximately
a 0° narrow high impact stream to a 60° wide fan
spray. (See Fig 8)
Figure 8 – Adjusting nozzle for fan pattern
(not applicable on some nozzles)
A narrow stream has high impact force on the
cleaning surface and results in maximum deep
cleaning in a concentrated area. However, this
narrow high impact spray must be used carefully
as it may damage some surfaces.
Figure 9 – Narrow high impact stream
A wide fan pattern will distribute the impact of the
water over a larger area, resulting in excellent
cleaning action with a reduced risk of surface
damage. Large surface areas can be cleaned
more quickly using a wide fan pattern.

NOZZLE CLEANING INSTRUCTIONS
A clogged or partially clogged nozzle
can cause a significant reduction of
water and may cause the unit to pulsate
while spraying. To clean out the nozzle:
•

Turn off and unplug the unit.
Turn off the water supply and relieve any
pressure within the unit by squeezing the trigger
2-3 times.
Separate the lance from the gun.
Rotate the nozzle to the narrow stream setting.
This opens up the fan blades.
Insert the cleaning needle (8) into the nozzle
hole and move it back and forth until the debris
is dislodged (Fig 11).
Fig 11
Remove additional debris by backflushing water
through the nozzle. To do this, place the end of
a garden hose (with water running) on the end
of the nozzle for 30-60 seconds.
